Message

At Aurelance, I architected and shipped a production SaaS from scratch, with a React frontend, a Node.js and Express API, and a MongoDB Atlas backend. I built 30+ REST endpoints and integrated Anthropic Claude for client sentiment analysis and contract risk scoring.

In paid client work, I delivered a financial backend with a six-state escrow engine and PayPal webhook signature validation. I also built production projects including ShopFlow, an e-commerce monorepo, and Airlock, a zero-trust task management system with live team presence and WebRTC file transfer.
